E+E Elektronik CO2 transmitters incorporate high-quality, dual-wavelength non-dispersive infrared (NDIR) CO2 measuring cells, which compensate for ageing effects, are highly insensitive to pollution and offer outstanding long term stability. The cells are assembled in state-of-the-art clean rooms and represent the prerequisite for highly accurate and long term stable CO2 measurement, especially for demanding applications such as agriculture, hatchers, incubators, greenhouses or life stock barns.
